Interesting that Ripley is front and centre there. In the movie the characters are killed off roughly from the most famous actor to the least famous one, eventually only leaving the completely unknown (at the time) Weaver, to make it look like she doesn't stand a chance against the alien.

Of course, today she's by far the biggest star in the cast, ironically thanks to the success of the movie, which kinda ruins this clever casting trick. I guess her name was already big by the time of the TV release.
